Hello, I am James McCartney. My undergrad is in informations systems and my masters is in information technology. I work professionally as a software developer and live outside Washington D.C USA.

I got involved in microelectronics as a hobby a few years ago and after some time 3d printing. I am pretty good using Sketchup and getting printable parts out of it as well as Eagle PCB CAD. I'll attach some pictures of my PCB work.
More pics.

I am Rainer Radow from Hannover, Germany.
My hobby's are all kind of techniques. During my life - I am 50 now - I became familiar with all kinds of electronics, and mechanics. My big passion are steamboats. I have build my steamboat Emma starting with an old 1930 riveted bare hull. Coal fired Boiler and 10 HP engine are self made: http://www.steamboating.de/emma/steam-bo...-main.html

For this I have a lathe and CNC mill at home. I also could mill Shellmo out of a block of aluminum ;-)
This part is 400 mm long:

Searching for a good method how to make cast iron patterns for a new steam engine I have build two RepRap printers. Because this was not the right tool for my purpose I lately finished a "Käsefräse" = Cheese Mill = German word for light CNC mill: http://cnc.radow.org/portal/cnc-portal-fraese-00-00.php

With this I milled some patterns for cast iron:

And got this part out of it - 20 kg of cast iron on the milling table:

I am also able to make my home brewed PCB's but more in the crude style with KiCad. I also changed from playing with chemicals to making it by CNC milling and drilling. So you also can form the outer contour in one step with the rest. Ideal for prototyping but limited by the minimum strip line -results are more like a breadboard!

Here 3 Arduino's with two comparators for signal amplifying

I am fascinated by the centipede movement and I would like to help making the design printable on the ordinary home 3D printer and durable to have fun with Shellmo.

I also like the/a shell for Shellmo - so we need designers too! Also eyes fascinates me.

I guess I was very distracted by you machining skills and creations (pics) that for some reason until just now did I realize when you meant "steamboat" you actually meant something you could ride in...followed your link..wow!

do you have already the motors for the RepSpider? Sho has send me some this summer as give away for Shellmo Enthusiasts - I could send such a pack with two motors, the motor driver and the BT-Module for free! Because I live in Hannover, Germany, this would be faster as if Sho would send it from Japan...
